Abstract
1440888 Endless-track vehicles CATERPILLAR TRACTOR CO 30 Aug 1974 [23 Jan 1974] 37943/74 Heading B7H In an endless-track tractor having a frame cross member 14 resting for rocking movement on an equalizer bar 16 bridging track frames 20, resilient masses 32 engaging the bar 14 to resist rocking movement thereof, and longitudinal frame members 12 which engage the bar 14 to partially restrict the extent of the rocking movement, there are provided additional stop means 50 arranged to engage the underside of the bar so as to act in concert with the members 12 to fully restrict the rocking movement and avoid overcompression of the resilient masses 32. Each stop means 50 comprises a barrel-shaped stop member 55 carried by a bolt 56 extending between plates 54 welded to the members 12 and/or to plates 26, 28 depending from the cross member 14. Guards 70 extend downwardly from a crankcase guard 72 ahead of the stop means 50 to protect them from damage. The resilient masses 32 are supported by subframes 30 depending from the crossmember 14 and carry wear plates 34 which receive projections 36 on the bar 16.
